[achievement brief introduction]
Content brief introduction: Use calcite (marble, limestone) manufacturing papermaking coating exceeds technology of fine calcium carbonate is a when in last few years development rises Chinese new and high technology. As the development of papermaking industry, the need of environmental protection, exceed fine calcium carbonate the dosage in papermaking is bigger and bigger already. Raw material: CaCO< , 3> is more than 95 ％ , whiteness is more than a mine of 90 ％ or 325 eye pink; Product index: Produce per year 5000 tons to exceed fine papermaking calcium carbonate, installation cost 80-120 10 thousand yuan, product price 1500-2000 yuan / ton, cost 500-800 yuan / ton, annual produce is controlled 2.5 million yuan, annual interest duty is controlled 1.2 million yuan. Produce per year 10000 exceed fine papermaking calcium carbonate, installation cost 200-250 10 thousand yuan, annual produce 750-1000 10 thousand yuan, 350-450 of annual interest duty 10 thousand yuan. Technological process: Raw ore - pink is ground - wet super- fine - dry - the product exceeds detailed technique. 85 ” of national “ science and technology tackles key problem achievement, 95 ” of national “ extend a plan mainly, progress of national science and technology is second-class award; Dry technology: 95 ” of national “ tackle key problem achievement. Main facility: Ramon is ground; MB or BP super- fine grind pare machine (pare a machine) , national level new product; Muti_function drier. Domestic demand makes an appointment with 20-30 10 thousand tons / year, at present domestic productivity makes an appointment with 100 thousand tons / year, as papermaking product line introduce, papermaking is measured with the beneficial result that exceeds fine calcium carbonate will bigger and bigger. Exceed product of fine calcium carbonate to still can be used at plastic, the industry such as printing ink coating.
